IMPROVED MACHINE FOR COVERING- ORD.

The Schedule referred to in these Letters Patent and makingpart of thesame.

To all whom. it may concern:

Be it known that we, THOMAS N. DALE, Jr., and GEORGE KRAJNK, of'Paterson, in the county ot' Passaic and State of N ew Jersey, hayeAinvented a new and useful Improvement in Covering Gord; and we dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the saine, reference being had to the accompanying drawingforming-part oi" this specification.

This invention .relates to improvements in machinery ihrcm-'eriug cottonor other material, for inaking hard or soft gimp, and consists inanarrangement of the Dobbins containing the covering-material on asupporting-disk or table, permanently attached to the frame, and atwister or covering-device iii connection therewith, in such 'a mannerthat the covering is accomplished bythe rotation ot' the twister.

The object is, by twisting the silk equally' around the cotton, to coverwith less silk than is -done in the ordinary manner, Where the silk andcotton are both twisted together, by ineans otan ordinary iiier, aroundeach other.

This ymachine twists them together too, but the twisting being donecentrally through a hollow spindle the cotton is kept in thecenter, andsilk is drawn up around it.

Figure 1 is va sectional elevation of our improved covering-machine, and

Figure z is a horizontal `section of the same.

Similar letters of reference indicate corresponding parts.'

A is the main frame, and

B is a horizontal table, permanently attached thereto.

It is preferably iliade circular in iorm, and has a number oi' spindles,C, arranged in aci'rcle on the top, to support the coveiing-bobbins D.

E is the bobbin tot the lcotton or other material to Vbe covered.

1tis-Inonnted horizontally below the said table, in suitable bearings,and the thread F is drawnup through the center of the table, and througha hollow `tube, and guide-plate H, to the covering or twisting-head l,which -is a revolving tube, in which the hole or passage for the threadis caused to diverge from the straight line, as shown ati K, for thevpurpose of straining it over the diverging wall, so as to cause thetwisting to be done between the said diver-ging point and tbeguide H,tln'oughthe slotted edge of which the covering-threads are drawn,previous to joining the cent-er thread at the lower end ofthe twister,into which both the center thread andthe cov,- ering are drawn to betwisted.

The drawing is effected by the grooved rollers L, mounted in thevertical part M on the top ofthe twister, and rotated by gearing with a.fixed wormwheel, N, in the axis ot' which the tube I turns.l

From these rollers the covered cord is conveyed, through the iers O, tothe bobbin F, mounted on the spindle Q, supported on the traversing railR, which is arranged to slide up `and down on the ways S, any suitablearrangement of means being employed to traverse it.

The covering-threads are passed through guides at T, and have weights Ususpended on them thereat, for tripping the belt-shifter in casethethread breaks.

These weights hang in vertical tubes V, supported on the table p -Theyfall upon the long arm of the lever W and throw itfdowu,v therebyraising the bent trippingrod X, having a stud, y, on the end on whichthe drop- -bar y is supported by the stud-pin Z, when the beltshifter Zis down, and the belt is running on the fast pulley Z2.

rlhe lever W is hollow, and containsA a rolling weight, which runs tothe outer end as soon as the weights U have tilted it slightly, andassists in carrying it down. v

By the above-descrihed arrangement ofthe revolving twister Y orcovering-device with the covering,l

bobhins on a fixed support, we are enabled to accomplish the work muchcheaper and a little better than when arranged in the common way, aswill be readily seen.

Instead of supporting the guide-plate H by the tube G, it may besupported by arms, connected to the frame above the table in anysuitable way.

l Having thus described our invention,

We lclaim as new and desire to secure by Letters Patcnt The combination,with the stand ortahle B and spindles C, ot' theguide-plate H, twistingor covering-bead, and the traversing spindle Q, all constructed andopera-ting as specitied.
